These photos were taken in 2005 by MisterPX of his custom AR-15 after 15,000 rounds of Wolf ammunition. He had lubed it every 1000 rounds but not cleaned it. A thousand rounds later a bolt lug sheared off and two magazines after that a second lug was lost and at that point he decided to terminate the experiment before something disastrous happened.

Those are my pics. I took those around the 15K mark. Broke a bolt lug around 16K, second lug broke after another mag or two, then I terminated my experiment. Interestingly enough, the bolt release broke in that 15-16 range as well.

… barrel was Bushy, BCG was M1S, think upper rec. was as well. Lower was a RRA, do not recall who’s LPK.

There is a discussion about this rifle and others at ARFCOM.
